Identifies the foam origin of all four terms in C₂ = 197/144 + π²/12 − π²ln2/2 + 3ζ (3) /4 = −0. 328479. The denominators (12, 144) are Ngauge and Ngauge². The threshold ln2 = ln (λEg/2) = ln ( (CA+1) /2), exact when CA=3. The winding coefficient 3/4 = CA/ (CA+1). The rational −91 = −λT2g× (F−1). Every constant is derived from UFFT. Zero free parameters. Status: structural identification; formal derivation from the two-loop D-mode path integral is the next step.
